The effects of mangosteen peel (Garcinia mangostana L.) and Turmeric (Curcuma domestica Val) flour dietary supplementation on the growth performance, lipid profile, and abdominal fat content in Cihateup ducks.

Bioactive compounds in mangosteen peel and turmeric have been shown to possess antioxidant and hypolipidemic properties.This study aimed to examine the effect of mangosteen peel flour (MF) and turmeric flour (TF) dietary supplementation on the performance, lipid profile, and abdominal fat content of Cihateup ducks.

The study was conducted for 56 days (8 weeks) using 84-day-old male Cihateup ducks that were allocated into seven treatments with three replications and each containing four ducks as subreplicates. The seven groups were positive control, containing 100% of basal ration/BR + 50 ppm bacitracin (R₀), BR + 2% MF (R₁), BR + 1.5% MF + 0.5% TF (R₂), BR + 1% MF + 1% TF (R₃), BR + 0.5% MF + 1.5% TF (R₄), BR + 2% TF (R₅), and BR only as negative control (R₆). The data of each variable were analyzed using a completely randomized design (one way). Significant differences (p<0.05) were determined with Duncan test.

The results indicated that the addition of MF and TF significantly affected (p<0.05) body weight, weight gain, mortality rate, low-density lipoprotein, high-density lipoprotein, and abdominal fat levels. At the same time, MF and TF significantly influenced (p<0.01) total cholesterol and triglyceride concentration. Non-significant differences (p>0.05) in feed intake and feed conversion of Cihateup ducks were observed.

The combination of MF and TF at a balanced ratio (R₃) can be used as an alternative feed additive to improve performance, lipid profile, and abdominal fat of Cihateup ducks.
